<Configuration of Heavy Running Detection Device According to First Embodiment>
With reference to FIG.2 and FIG.3, the structure of the heavy-running detection apparatus which concerns on 1st Embodiment is demonstrated. FIG. 2 is a schematic side view of the heavy running detection device 100 according to the first embodiment. FIG. 3 is a schematic front view of the heavy running detection device 100 according to the first embodiment. In FIG. 3, the description of the conveyance path 20 shown in FIG. 2 is omitted.

  The heavy running detection device 100 is a device that detects whether or not the booklet medium 10 inserted from the passbook insertion / extraction port 2 is in a double feed state in which the booklet medium 10 is inserted in an overlapping manner. A booklet-like medium 10 assumed in the present embodiment has a cover 11 and a sheet 12, and can be opened and closed around a binding line 13 as an axis. A material harder than the paper 12 is used for the cover 11 of the booklet medium 10.

  The heavy-running detection device 100 includes a conveyance path 20, an insertion detection sensor 25, a brake start sensor 26, a length detection sensor 27, an upper roller 30, a drive unit 40 (FIG. 3), a lower roller 50, A torque limiter mechanism 60 (FIG. 3), a second roller 70, a storage unit 80, and a control unit 90 are provided. The heavy run detection device 100 is disposed in the automatic transaction apparatus 1 at a position close to the passbook insertion / extraction port 2. Hereinafter, each device will be described. In the first embodiment, the upper roller 30 is a first transport roller, and the lower roller 50 is a second transport roller. Further, the upper roller 30, the drive unit 40, and the lower roller 50 may be collectively referred to as a conveyance unit.

(Conveyance path)
The conveyance path 20 includes an upper conveyance guide plate 21 and a lower conveyance guide plate 22 that faces the upper conveyance guide plate 21 at a predetermined interval. Thereby, a fixed space is formed between the upper conveyance guide plate 21 and the lower conveyance guide plate 22, and the booklet medium 10 inserted from the passbook insertion / extraction port 2 is transferred to the upper conveyance guide plate 21 and the lower conveyance guide plate. The space formed by 22 is moved in the transport direction. Here, the passbook insertion / extraction port 2 is opened so that the axial direction of the binding 13 of the booklet-shaped medium 10 is orthogonal to the transport direction and the cover 11 is on the lower side (the side on which the lower roller 50 is disposed). In this state, the booklet-like medium 10 is inserted, and the booklet-like medium 10 inserted into the passbook insertion / extraction port 2 is conveyed in the conveyance path 20 in that state. Hereinafter, a page in the conveyance direction of the booklet-shaped medium 10 may be referred to as a front page portion, and a page in a direction opposite to the conveyance direction may be referred to as a rear page portion (see FIG. 4).

  The upper conveyance guide plate 21 and the lower conveyance guide plate 22 are formed of a non-conductive mold (plastic) material. The upper conveyance guide plate 21 is provided with a rectangular cutout for projecting part of the upper roller 30 and the second roller 70. Further, the lower conveyance guide plate 22 is provided with a rectangular cutout for projecting a part of the lower roller 50 and the second roller 70 so as to face the position of the cutout.

(Insertion detection sensor)
The insertion detection sensor 25 is an optical sensor and detects the insertion of the booklet medium 10 into the passbook insertion / extraction port 2 by the operator of the automatic transaction apparatus 1. The insertion detection sensor 25 outputs an “ON” signal to the control unit 90 while the booklet-shaped medium 10 exists immediately below the insertion detection sensor 25.

(Upper roller)
The upper roller 30 has a cylindrical shape, and a shaft 31 orthogonal to the conveyance direction passes through the upper roller 30. The upper roller 30 is rotatable about the shaft 31 as a rotation axis. The upper roller 30 has a peripheral surface that contacts the booklet-shaped medium 10 in a rotating state, and transmits a propulsive force in the transport direction to the booklet-shaped medium 10 using a frictional force between the peripheral surface and the booklet-shaped medium 10. . The peripheral surface of the upper roller 30 is formed of an elastic body such as rubber.

(Drive part)
The drive unit 40 is connected to one end of the shaft 31, and when the insertion detection sensor 25 detects the insertion of the booklet medium 10 into the passbook insertion / discharge port 2, the drive unit 40 generates a driving force for rotating the upper roller 30 in the direction of the broken line arrow. It is applied via the shaft 31. The drive unit 40 includes, for example, a motor and a gear.

(Lower roller)
The lower roller 50 has a cylindrical shape, and is provided at a position facing the upper roller 30 across the conveyance path 20 through a shaft 51 orthogonal to the conveyance direction. The lower roller 50 is rotatably supported with the shaft 51 as a rotation axis.
Since the drive unit 40 is connected to the shaft 31 of the upper roller 30, the upper roller 30 can rotate by itself, but the device for applying the drive force is not connected to the shaft 51 of the lower roller 50. So it cannot rotate on its own. Therefore, the lower roller 50 follows the rotational movement of the upper roller 30 and rotates in the direction of the broken arrow. Specifically, when the booklet-shaped medium 10 advances in the transport direction in a state where the peripheral surface of the lower roller 50 is in contact with the booklet-shaped medium 10, the direction of the broken line arrow indicates the friction force between the peripheral surface and the booklet-shaped medium 10. Rotate to. The peripheral surface of the lower roller 50 is formed of an elastic body such as rubber.

(Brake start sensor)
The brake start sensor 26 is an optical sensor and is a device for controlling the timing at which the rotational movement of the lower roller 50 is suppressed (brake applied) using the torque limiter mechanism 60. The brake start sensor 26 can change the timing of suppressing (braking) by changing the position where the brake start sensor 26 is disposed. The brake start sensor 26 outputs an “ON” signal to the control unit 90 while the booklet-shaped medium 10 exists immediately below the brake start sensor 26.

  The heavy running detection device 100 according to the present embodiment is configured to suppress the rotational movement of the lower roller 50 in a state where the front page portion of the booklet-like medium 10 is sandwiched between the upper roller 30 and the lower roller 50. Has been. For this reason, the heavy-running detection device 100 causes the front end of the booklet medium 10 to pass through the brake start sensor 26 until the binding 13 of the booklet medium 10 comes to the upper roller 30 (or the lower roller 50). In addition, the brake start sensor 26 is disposed close to the upper roller 30 (or the lower roller 50).

  On the other hand, in the case where the rear page portion of the booklet-like medium 10 is held between the upper roller 30 and the lower roller 50 and the rotational movement of the lower roller 50 is suppressed, Brake start sensor so that the leading edge of the booklet medium 10 passes through the brake start sensor 26 until the binding 13 of the booklet medium 10 reaches the roller 30 (or the lower roller 50) and the end of the booklet medium 10. 26 is disposed relatively apart from the upper roller 30 (or the lower roller 50).

  In addition to changing the position where the brake start sensor 26 is disposed, the position of the brake start sensor 26 is fixed, and the detection time of the leading edge of the booklet medium 10 by the brake start sensor 26 and the rotation speed of the upper roller 30 are May be used to adjust the timing to be suppressed (brake applied) by the control unit 90.

(Torque limiter mechanism)
The torque limiter mechanism 60 applies braking torque and releases the braking torque when the braking torque reaches a predetermined value. That is, the torque limiter mechanism 60 is a mechanism that generates a constant load (rotation suppression torque) in the rotation direction, and idles when the load that can be generated is exceeded. The torque limiter mechanism 60 is disposed in the vicinity of the lower roller 50 and is connected to the shaft 51 of the lower roller 50 at a timing when a brake start instruction is notified from the brake start sensor 26. Any connection method may be used as long as the torque generated by the torque limiter mechanism 60 can be transmitted to the lower roller 50. For example, a method of moving the torque limiter mechanism 60 or a method of using a clutch may be used. When the torque limiter mechanism 60 is connected to the shaft 51 of the lower roller 50, the torque limiter mechanism 60 applies a rotation suppression torque (braking force) that suppresses the rotational movement of the lower roller 50 in the direction of the broken line arrow. As a result, the rotation of the lower roller 50 stops.

  When the booklet-like medium 10 moves in the transport direction in a state where the lower roller 50 is stopped by the braking force of the torque limiter mechanism 60, the booklet-like medium 10 is caused to frictional force (braking force) against the propulsive force from the lower roller 50. Receive. Accordingly, the booklet-shaped medium 10 generates a shearing force having the same magnitude as the frictional force (braking force) inside. The heavy running detection device 100 performs heavy running detection using a shearing force generated inside the booklet-shaped medium 10. That is, since the rigidity of the booklet-shaped medium 10 exceeds the shearing force if the booklet-shaped medium 10 is not overlapped (if it is a non-heavy-running medium), the heavy-running detection device 100 is long in the transport direction of the booklet-shaped medium 10. However, if the booklet-like media 10 are overlapped (if they are heavy-running media), the frictional force between the overlapping booklet-like media 10 is less than the shearing force. The mediums 10 are displaced from each other, and the length in the transport direction of the heavy running medium is increased. The heavy running detection device 100 determines whether the booklet medium 10 in the conveyance path is a heavy running medium based on the length of the booklet medium 10 in the conveyance direction. Details will be described in the operation of the heavy running detection device 100.

  The torque limiter mechanism 60 is configured to idle when the load that can be generated (rotation suppression torque) is exceeded, so that the lower roller 50 detects the heavy running of the booklet-like medium 10. The occurrence of clogging of the booklet medium 10 due to the application of the braking force can be reduced. In addition, if the booklet medium 10 is jammed on the conveyance path 20, even if the jammed booklet medium 10 is pulled out, the lower roller 50 is idled, so that the heavy running detection device 100 is broken or the medium is damaged. Can be prevented.

  Here, a range (section) in which the torque limiter mechanism 60 applies a rotation suppression torque (braking force) that suppresses the rotational motion of the lower roller 50 when performing heavy running detection of the booklet-shaped medium 10 is shown in FIG. Thus, it is limited to the front page portion of the booklet-like medium 10. As described above, the brake start position is controlled based on the position of the brake start sensor 26, and the brake release position is determined based on the rotational speed of the upper roller 30 from the brake start position and the circumferential length of the upper roller 30. 10 movement distances are calculated and controlled. The reason why the range (section) in which the torque limiter mechanism 60 applies torque (braking force) that suppresses the rotational movement of the lower roller 50 is limited to the front page portion of the booklet-shaped medium 10 is as follows.

That is, as shown in FIG. 5A, the range in which the torque limiter mechanism 60 (see FIG. 3) applies the rotation suppression torque (braking force) that suppresses the rotational movement of the lower roller 50 is the front page of the booklet-shaped medium 10. In the case of a portion, the propulsive force 16 acting on the booklet-shaped medium 10 becomes a pulling force on the paper 12, and the braking force 17 acting on the booklet-shaped medium 10 becomes a compressive force on the cover 11.
On the other hand, as shown in FIG. 5B, the range in which the torque limiter mechanism 60 (see FIG. 3) applies the rotation suppression torque (braking force) that suppresses the rotational motion of the lower roller 50 is the rear page of the booklet-shaped medium 10. In the case of a portion, the driving force 16 acting on the booklet-shaped medium 10 becomes a compressive force on the paper 12, and the braking force 17 acting on the booklet-shaped medium 10 becomes a pulling force on the cover 11.

  Here, since the sheet 12 is generally weaker in compressive force than the pulling force, when the braking force is applied to the rear page portion of the booklet-like medium 10, the sheet 12 is placed as shown in FIG. I will turn over. Since the cover 11 is generally made of a material harder than the paper 12, the paper 11 is turned as shown in FIG. 5 (a) even if it is weaker in compressive force than in the tensile force. There is nothing. For this reason, the torque limiter mechanism 60 limits the range in which the braking force is applied to the lower roller 50 to the front page portion of the booklet-like medium 10.

(Second roller)
Returning to FIG. 2, the second roller 70 applies a driving force in the transport direction to the booklet-shaped medium 10 that has passed through the upper roller 30 and the lower roller 50, and pulls the booklet-shaped medium 10 further into the automatic transaction apparatus 1. . The second roller 70 may be configured to apply a propulsive force in the transport direction to the booklet-shaped medium 10. For example, the second roller 70 may have the same configuration as the upper roller 30 and the lower roller 50, or other configurations. It doesn't matter.

(Length detection sensor)
The length detection sensor 27 is an optical sensor, and is a sensor for detecting the length of the booklet-shaped medium 10 in the conveyance direction, and the booklet-shaped medium 10 exists immediately below the length detection sensor 27. In this case, an “ON” signal is output.

(Memory part)
The storage unit 80 is composed of storage media such as a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), and a flash memory, and is required for various operations required for the operation of the passbook printer of the automatic transaction apparatus 1. Is stored. For example, the storage unit 80 stores information related to the size of the booklet-shaped medium 10, the size and rotation speed of the upper roller 30, position information of the sensors 25, 26, and 27.

(Control part)
The control unit 90 is realized by a program execution process by a CPU (Central Processing Unit), a dedicated circuit, and the like, and realizes various functions necessary for the operation of the passbook printing apparatus of the automatic transaction apparatus 1. For example, the control unit 90 realizes control of the drive unit 40 and the torque limiter mechanism 60 based on signals received from the sensors 25, 26, 27, heavy running determination based on signals received from the sensors 25, 26, 27, and the like. To do. Below, the part which implement | achieves heavy run determination among control parts may be called the "heavy run determination part 91". The details of the control unit 90 will be described in the operation of the heavy running detection device 100.
Above, the description regarding the structure of the heavy-running detection apparatus which concerns on 1st Embodiment is complete | finished.

<Operation of Heavy Running Detection Device According to First Embodiment>
With reference to FIG. 7 (refer to FIGS. 2 to 6 as appropriate), the operation of the heavy-running detection device 100 according to the first embodiment will be described. FIG. 7 is a flowchart showing the operation of the heavy-running detection device 100 according to the first embodiment.

  First, the operator of the automatic transaction apparatus 1 inserts the booklet-like medium 10 through the passbook insertion / extraction port 2. The control unit 90 receives the “ON” signal from the insertion detection sensor 25, operates the driving unit 40, and applies a driving force to the upper roller 30. Thereby, in the heavy running detection device 100, the rotational force is transmitted from the driving unit 40 to the upper roller 30, and the upper roller 30 starts to rotate. When the upper roller 30 rotates, the booklet medium 10 is sandwiched between the upper roller 30 and the lower roller 50 and conveyed to the back (conveying direction) of the automatic transaction apparatus 1. At this time, since the lower roller 50 is in contact with the booklet-shaped medium 10, it is dragged and rotated (step S 10).

  Subsequently, the booklet-shaped medium 10 is transported in the transport direction, and the leading end of the booklet-shaped medium 10 reaches the brake start sensor 26 (step S20). The control unit 90 receives the “ON” signal from the brake start sensor 26 and connects the torque limiter mechanism 60 to the lower roller 50 (step S30). As a result, the lower roller 50 receives a rotation suppression torque (braking force) that suppresses the rotational movement of the lower roller 50. The rotation suppression torque (braking force) is a force in the direction opposite to the rotation direction in which the booklet medium 10 is conveyed. The rotation of the lower roller 50 is stopped by the rotation suppression torque (braking force).

  First, as shown in FIG. 5A, one booklet-shaped medium 10 is inserted into the passbook insertion / exhaust port 2 (see FIG. 2) without being overlapped, and one booklet-shaped medium 10 is not overlapped. Consider a case in which a non-heavy traveling medium that moves on the conveyance path 20 (see FIG. 2) exists. The booklet-shaped medium 10 includes a propulsion force 16 in the conveying direction and a frictional force (braking force 17) generated between the peripheral surface of the lower roller 50 and the booklet-shaped medium 10 on the lower roller 50 side. Shear force is generated.

  However, since the rigidity of the booklet-shaped medium 10 exceeds the shearing force, the booklet-shaped medium 10 moves in the transport direction against the frictional force. When the booklet-shaped medium 10 advances to the brake release position (step S40), the control unit 90 disconnects the torque limiter mechanism 60 and the shaft 51 of the lower roller 50 (withdraws the torque limiter mechanism 60), The application of the rotation suppression torque (braking force) that suppresses the rotational movement of the roller 50 is canceled (step S50). When one booklet medium 10 is inserted without being overlapped, the length of the booklet medium 10 in the transport direction is the same as the specified size stored in the storage unit 80.

  On the other hand, as shown in FIG. 6 (a), a plurality of booklet-like media 10 are inserted into the passbook insertion / exhaust port 2 (see FIG. 2) in an overlapping manner (FIG. 6 (a) shows two booklet-like media 10 as an example. Suppose that a plurality of booklet-shaped media 10 exist as heavy-running media that run through the transport path 20 (see FIG. 2) while they are overlapped. In the heavy running medium in which a plurality of booklet-like media 10 are overlapped, there is a frictional force generated between the propulsive force 16 in the transport direction and the booklet-like medium 10 on the peripheral surface of the lower roller 50 and the lower roller 50 side ( A shearing force is generated by the braking force 17).

  Since the plurality of booklet-like media 10 overlap each other, the booklet-like medium 10 on the upper roller 30 side is conveyed in the conveyance direction by the propulsion force 16, while the booklet-like medium 10 on the lower roller 50 side. Remains in place without being conveyed by the braking force 17. Along with this, the plurality of booklet-shaped media 10 that have been run over are in a state in which the length in the transport direction has increased compared to the state in which the plurality of booklet-like media 10 are initially sandwiched between the upper roller 30 and the lower roller 50. That is, the booklet-shaped medium 10 is shifted. Then, as shown in FIG. 6B, when the booklet medium 10 on the upper roller 30 side advances to the brake release position (step S40), the control unit 90 includes the torque limiter mechanism 60 and the shaft 51 of the lower roller 50. Is disconnected (the torque limiter mechanism 60 is retracted), and the application of the rotation suppression torque (braking force) that suppresses the rotational movement of the lower roller 50 is released (step S50).

  Subsequently, the booklet-shaped medium 10 passes through the second roller 70, and then the control unit 90 turns “ON” from the length detection sensor 27 when the tip of the booklet-shaped medium 10 reaches the length detection sensor 27. A signal is received, and an “OFF” signal is received from the brake start sensor 26 when the end of the booklet medium 10 reaches the brake start sensor 26. The control unit 90 is inserted using the time from the time when the “ON” signal is received from the length detection sensor 27 to the time when the “OFF” signal is received from the brake start sensor 26 and the distance between the two sensors. The length of the booklet medium 10 in the conveyance direction is calculated (step S60). If the medium that has been inserted is a heavy-duty medium, the booklet-shaped medium 10 that is vertically stacked is displaced by the braking force of the lower roller 50, and the overall length is long. If the total length of the booklet medium 10 obtained from the ON / OFF time of the sensor is equal to or larger than the specified size stored in the storage unit 80, the heavy running determination unit 91 of the control unit 90 has two or more booklet mediums 10 stacked. Is inserted (step S70) and returned from the passbook insertion / extraction port 2. On the other hand, if the total length of the booklet-shaped medium 10 obtained from the sensor ON / OFF time is the same as the specified size stored in the storage unit 80, the heavy-duty determination unit 91 inserts one booklet-shaped medium 10. (Step S70), and the subsequent processing is performed.

In the heavy running determination, it is the torque limiter mechanism 60 that applies the braking force to the lower roller 50. The torque limiter mechanism 60 is idled when a certain torque or more is applied. Therefore, the lower roller 50 is not completely fixed, and the lower roller 50 can rotate when a torque exceeding a certain level is applied. If the booklet-shaped medium 10 is clogged with the lower roller 50 and the torque limiter mechanism 60 connected and is forcibly pulled out by the operator, the lower roller 50 is rotated to rotate the automatic transaction apparatus 1 or the booklet-shaped medium. 10 breakage can be prevented.
Above, description about operation | movement of the heavy run detection apparatus which concerns on 1st Embodiment is complete | finished.

  As described above, in the heavy running detection device 100 according to the first embodiment, the lower roller 50 that generates the braking force has the booklet-like medium 10 because the rigidity of the booklet-like medium 10 exceeds the shear force in the non-multifeed state. There is no hindrance to the transport. On the other hand, in the double feed state in which a plurality of booklet-like media 10 are overrun, the heavy run detection device 100 according to the first embodiment first applies the braking force by the lower roller 50, so The overlapped booklet medium 10 is in a state in which the length is increased in the transport direction as compared with the state of being sandwiched between the lower roller 50. Thereby, the heavy running detection device 100 can detect the double feed state by the length detection sensor 27. Moreover, since the heavy-running detection device 100 according to the first embodiment is a torque limiter method, the torque limiter mechanism 60 is moved to the lower part if the booklet-like medium 10 is jammed on the transport path 20 and cannot be transported, or by mischief. Even if the booklet-like medium 10 is pulled out while connected to the roller 50, the lower transaction roller 50 idles with a load of a certain level or more, so that the automatic transaction apparatus 1 and the booklet-like medium 10 are not damaged.

  Further, the heavy running detection device 100 according to the first embodiment generates a braking force on the lower roller 50 based on a signal from the brake start sensor 26 and shifts the booklet-like medium 10 to shift the booklet-like medium 10 to two or more booklet-like media 10. Therefore, it is not affected by the thickness of the booklet medium 10, the number of pages, and the spread pages. Therefore, it can be used for the passbook printing apparatus of the automatic transaction apparatus 1 that handles a plurality of types of booklet-like media 10 simultaneously.

  Moreover, since the heavy-running detection device 100 according to the first embodiment cannot determine whether or not a plurality of booklet-like media 10 are overlapped at the time when the booklet-like media 10 are inserted into the passbook insertion / exhaust port 2, Even in this case, the braking force is applied to the lower roller 50. However, by limiting the section in which the braking force is generated to the lower roller 50 to the front page portion from the joint 13 of the booklet medium 10, the booklet medium 10 ( In particular, the paper 12) can be prevented from being damaged.

[Second Embodiment]
In the heavy running detection device 100 according to the first embodiment, the lower roller 50 is rotated following the upper roller 30. On the other hand, the heavy-running detection device 100a according to the second embodiment keeps the torque limiter mechanism 60 connected to the lower roller 50 at all times and separates it from the shaft 51 that pivotally supports the lower roller 50 at an arbitrary timing. Connectable drive unit 40a.
Thereby, since the heavy-running detection device 100a according to the second embodiment rotates with the driving force not only on the upper roller 30 but also on the lower roller 50, the slip-like material 10 is used or the deformation is performed. A sufficient propulsive force can be ensured even under conditions where the transport force tends to be insufficient, such as when the booklet-shaped medium 10 is used or when the booklet-shaped medium 10 is used in a low temperature state.

<Configuration of Heavy Run Detection Device According to Second Embodiment>
With reference to FIG. 8, the structure of the heavy-running detection apparatus which concerns on 2nd Embodiment is demonstrated. FIG. 8 is a schematic front view of the heavy running detection device 100a according to the second embodiment. In FIG. 8, the conveyance path 20 (see FIG. 2) is not shown.

  The difference between the heavy run detection device 100 according to the first embodiment and the heavy run detection device 100a according to the second embodiment is that the drive unit 40a is added and the torque limiter mechanism 60 is replaced with the torque limiter mechanism 60a. This is a change. Below, only the structure changed from 1st Embodiment among the structures of the heavy run detection apparatus 100a which concerns on 2nd Embodiment is demonstrated. In the second embodiment, the upper roller 30 is a first transport roller, and the lower roller 50 is a second transport roller.

(Drive part)
The drive unit 40a is detachably connected to one end of the shaft 51, and applies a driving force (torque) for rotating the lower roller 50 through the shaft 51 in the connected state. The driving force (torque) applied by the driving unit 40a is set larger than the braking force (rotation suppression torque) suppressed by the torque limiter mechanism 60a. The drive unit 40a includes, for example, a motor and a gear. Any method may be used for separating the drive unit 40a as long as the torque generated by the drive unit 40a is not transmitted to the lower roller 50. For example, a method using a clutch may be used. The drive unit 40a is disconnected at the timing when the brake start instruction is notified from the brake start sensor 26.

(Torque limiter mechanism)
The torque limiter mechanism 60a is always connected to the shaft 51 of the lower roller 50. The rest is the same as the torque limiter mechanism 60 according to the first embodiment.
Above, the description regarding the structure of the heavy-running detection apparatus which concerns on 2nd Embodiment is complete | finished.

<Operation of Heavy Running Detection Device According to Second Embodiment>
With reference to FIG. 9 (refer FIG. 8 suitably), operation | movement of the heavy running detection apparatus 100a which concerns on 2nd Embodiment is demonstrated. FIG. 9 is a flowchart showing the operation of the heavy running detection device 100a according to the second embodiment.

  First, the operator of the automatic transaction apparatus 1 inserts the booklet-like medium 10 through the passbook insertion / extraction port 2 (see FIG. 2). The control unit 90 receives the “ON” signal from the insertion detection sensor 25, operates the driving unit 40 and the driving unit 40 a, and applies driving force to the upper roller 30 and the lower roller 50. As a result, in the heavy running determination device 100a, the rotational force is transmitted from the drive unit 40 to the upper roller 30 and the upper roller 30 starts to rotate, and the rotational force is transmitted from the drive unit 40 to the lower roller 50 and the lower roller 50 is The rotation is started (step S10a). At this time, the rotation speeds of the upper roller 30 and the lower roller 50 (peripheral speed of the roller outer periphery) must be the same.

  Subsequently, when the booklet-shaped medium 10 is sandwiched between the upper roller 30 and the lower roller 50 that rotate together, the booklet-shaped medium 10 is conveyed in the conveying direction, and the leading end of the booklet-shaped medium 10 is the brake start sensor 26 (FIG. 2). Reference) is reached (step S20). The control unit 90 receives the “ON” signal from the brake start sensor 26 and disconnects the drive unit 40a from the lower roller 50 (step S30a). As a result, the drive torque of the drive unit 40a is not transmitted to the lower roller 50, and the torque transmitted to the lower roller 50 is a rotation suppression torque (brake force) that suppresses the rotational motion of the lower roller 50 provided from the torque limiter mechanism 60a. ) Only. The rotation suppression torque (braking force) is a force in the direction opposite to the rotation direction in which the booklet medium 10 is conveyed. The rotation of the lower roller 50 is stopped by the rotation suppression torque (braking force).

The phenomenon that occurs in the booklet-shaped medium 10 when the rotation of the lower roller 50 stops is the same as in the first embodiment. When the booklet-shaped medium 10 advances to the brake release position (step S40), the control unit 90 reconnects the driving unit 40a to the lower roller 50, and applies a driving torque that is equal to or greater than the load generated by the torque limiter mechanism 60a. Thus, the brake force is removed (the brake force is canceled) (step S50a). Subsequent heavy run determination is the same as in the first embodiment.
Above, description regarding operation | movement of the heavy-running detection apparatus which concerns on 2nd Embodiment is complete | finished.

  As described above, the heavy-running detection device 100a according to the second embodiment rotates not only the upper roller 30 but also the lower roller 50 with a driving force. For this reason, the heavy-running detection device 100a according to the second embodiment has a conveyance force when using a booklet medium 10 made of a slippery material, when using a deformed booklet medium 10, or when used in a low temperature condition. It is possible to ensure a sufficient propulsive force even under conditions that make it easy to run out.

[Third Embodiment]
The heavy run detection device 100 according to the first embodiment and the heavy run detection device 100a according to the second embodiment both include a plurality of cases when the inserted booklet medium 10 is a single book (in the case of a non-heavy run medium). Even when they are stacked (in the case of a heavy-duty medium), the brake operation is performed regardless of the situation.
Therefore, when the booklet-like medium 10 is a single book (in the case of a non-heavy running medium), a slip occurs between the booklet-like medium 10 and the upper roller 30 or between the booklet-like medium 10 and the lower roller 50. It will be. There is no problem in the function of detecting the overlapped booklet medium 10, but there is a possibility that the surface of the booklet medium 10 may become dirty due to the occurrence of slip. Further, when a slip occurs between the upper roller 30 and the booklet-shaped medium 10, it seems as if the transport of the booklet-shaped medium 10 is temporarily stopped during that time. The third embodiment is configured with these points in mind.

<Configuration of Heavy Run Detection Device According to Third Embodiment>
The configuration of the heavy run detection device 100b (not shown) according to the third embodiment is the same as the configuration of the heavy run detection device 100 according to the first embodiment. However, the braking force applied from the torque limiter mechanism 60 to the lower roller 50 is the mutual force necessary for shifting the booklet-shaped medium 10 when a plurality of booklet-shaped mediums 10 are overlapped and inserted (in the case of a heavy-running medium). Of the booklet medium 10 and the upper roller 30 or the lower part when the booklet medium 10 is inserted (in the case of a non-heavy running medium). It is set to be smaller than the force that causes slip between the roller 50 (maximum static frictional force between the booklet medium 10 and the upper roller 30 or the lower roller 50).

That is, the brake force limiter (upper limit value) applied from the torque limiter mechanism 60 to the lower roller 50 is set so as to satisfy the following condition.
<Setting conditions for brake force limiter (upper limit)>
The maximum static friction force between the booklet media 10 <the limiter of the braking force of the torque limiter mechanism 60 (upper limit value) <the maximum static friction force between the booklet media 10 and the upper roller 30 or the lower roller 50 The driving force applied by the portion 40 to the upper roller 30 is set to be stronger than the brake force limiter (upper limit value).
Above, the description regarding the structure of the heavy-running detection apparatus which concerns on 3rd Embodiment is complete | finished.

<Operation of Heavy Running Detection Device According to Third Embodiment>
Since the operation of the heavy run detection device 100b (not shown) according to the third embodiment is the same as that of the heavy run detection device 100 according to the first embodiment, the description thereof is omitted.

  As described above, the heavy-running detection device 100b (not shown) according to the third embodiment sets the limiter (upper limit value) of the braking force applied from the torque limiter mechanism 60 to the lower roller 50 as “between the booklet-shaped media 10. The maximum static friction force <the brake force limiter (upper limit value) of the torque limiter mechanism 60 <the maximum static friction force between the booklet medium 10 and the upper roller 30 or the lower roller 50 ”. Thereby, when a plurality of booklet-like media 10 are inserted in a stacked manner (in the case of a heavy-duty medium), the booklet-like media 10 can be displaced, and when a booklet-like medium 10 is inserted ( In the case of a non-heavy travel medium), the torque limiter mechanism 60 starts idling before slip occurs between the upper roller 30 and the lower roller 50. For this reason, the heavy-running detection device 100b (not shown) according to the third embodiment has no possibility of causing contamination on the surface of the booklet-like medium 10 due to the occurrence of slip, and the booklet-like medium 10 can be transported. There is no temporary stop.
